ADV7800

Hi,

    We don't do it for each format.  We don't know that it's linear with pixel clock-- only some of the power consumption is dynamic. We generally recommend people design for the max.  If you want to design for a lesser amount, I'd recommend testing power consumption at that resolution".

   Yes the external memory is required only for 3D comb, DNR, and frame TBC. Memory configuration options for the external SDRAM are provided in Table 51.

    If we are not using such functionality(3D comb) then the external SDRAM memory is not required.

Any particular sequencing required? 

The following power on/off sequence is recommended for the ADV7800:
1. DVDDIO
2. AVDD
3. DVDDIO_SRAM
4. DVDD/PVDD
As the list indicates, it is recommended that, for example, the DDVDIO_SRAM should power up
after the AVDD.

Please refer Page 238 in ADV7800_HW_RevB.Pdf.

Thanks,
